电梯和自动扶梯上的传感器

Application of Sensors in Elevators and Escalators

介绍了电梯和自动扶梯上通常用到的传感器,描述了它们对电梯和自动扶梯正常运行、安全运行所起的作用。内容包括电梯测速、抱闸、平层、门控等控制环节所用传感器,和自动扶梯电机测速、入口探测、进出口检测、扶手带测速、梯级丢失等控制环节所用传感器。

The sensors commonly used in elevators and escalators are introduced in this paper, as well as their roles in normal and safe operation of elevators and escalators, which include those adopted in speed measurement, brake detection, level control and door control of elevators, and motor speed measurement, entrance detection, inter-exit detection, handhold belt speed measurement and step missing detection of escalators.
